If you’re hoping to replace missing upper back teeth with dental implants but have been told there isn’t enough bone height beneath your sinus, a sinus lift can make implants possible. Using 3D CBCT imaging and gentle techniques, our doctors safely add bone support in the upper jaw so your new implants stay strong and secure for years to come.
What is a sinus lift (sinus augmentation)?
Your maxillary sinuses are air-filled cavities located behind your cheeks, directly above your upper back teeth. When natural upper molars or premolars are removed, the ridge of bone that once supported them naturally melts away over time. Without intervention, there may only be a paper-thin layer of bone separating your mouth from your sinus cavity—far too little bone to safely anchor a titanium dental implant post.
Precision access
Using high-definition 3D CBCT digital imaging, our surgical team maps your sinus anatomy with sub-millimeter precision and creates a microscopic opening in the upper jawbone near the missing tooth site.
Elevating the membrane
The delicate membrane lining the maxillary sinus cavity (the Schneiderian membrane) is gently elevated upward, creating a protected space between your upper jawbone and the sinus floor.
Placing the graft material
Specialized biocompatible bone grafting material is meticulously placed into the newly created space beneath the raised sinus membrane to build up essential bone height.
Natural bone regeneration
Over the next several months, your body naturally integrates the graft material, transforming it into strong, dense living bone that safely houses permanent dental implants.
Relaxing, anxiety-free surgery with sedation dentistry
We recognize that any procedure involving the sinuses can sound intimidating to patients. At Sunrise Dental Everett, your comfort and peace of mind are our highest priority.
To ensure your surgical visit is entirely stress-free, we provide a full spectrum of comfortable sedation dentistry options—including soothing nitrous oxide (laughing gas), oral conscious sedation, and deep IV sedation. Deeper sedation options allow you to drift into a peaceful, sleep-like state. You will feel zero pain, experience no pressure or anxiety, and wake up comfortably with little to no memory of the surgery.
Why might you need a sinus lift?
Our surgical team in Everett evaluates your upper jaw architecture with 3D CBCT imaging during your implant consultation. A sinus lift is commonly recommended if you experience any of the following.
Missing upper molars or premolars leads to progressive bone resorption, causing the sinus floor to expand downward into the space formerly occupied by tooth roots.
Some individuals naturally have larger maxillary sinus cavities or thin alveolar ridges, requiring supplementary bone height before dental implants can be anchored.
Advanced periodontal disease can erode the supporting bone structure around upper teeth before or after extraction, leaving insufficient bone volume for implant stability.
